Low-Emission Plug Valve
Flowserve engineered the Durco® G4XZ low-emission plug valve to perform reliably and guarantee compliance with probably the most stringent ISO and API fugitive emissions requirements, including ISO 15848-1-BH-CO3 and API 641 1st version. The G4XZ valve can be used in hydrofluoric acid (HF) alkylation industry processes together with:
Blending
Crude desalting
Gas crops
Isomerization
Light ends
Sulphur vegetation
Chlorine
Anhydrous hydrochloric acid (HCl)
Hydrofluoric acid (HF)
The versatile G4XZ valve also can be used for deadly, poisonous and sub-zero fluid services similar to chlorine, anhydrous hydrogen chloride, phosgene, propylene oxide, isobutane and HF acid.
Reduced fugitive emissions
Operators can set up the Durco G4XZ valve with confidence in purposes with volatile air pollution and dangerous fluids. The Durco G4XZ valve design has undergone rigorous testing and is licensed to the most stringent trade requirements, together with ISO 15848-1-BH-CO3 (2,500 mechanical cycles) and API 641 1st version.
Engineered for safety
The G4XZ valve ensures increased plant and personnel security via its fire-safe design and construction that complies with API 607 7th edition and ISO 10497 2010 fire-safe standards (for external leakage only).
Improved reliability and uptime
The tight shut-off efficiency is repeatable and dependable to reduce unexpected downtime; The G4XZ valve design doesn’t require lubrication for sealing. Instead, the plug can merely be adjusted additional into the sleeve to enhance sealing functionality.
Simplified, in- เกจวัดแรงดันลม10bar , packing and top cap seal that allow easy adjustment or re-energization of seals as needed.
